Yes, I do acknowledge that aussie fuel is not as great as JDM fuel and do play a part of carbon build up. That's common knowledge floating amongst most EP3 owners.
However, I am interested to understand what the OEM ecu is "naturally" doing to richen up the fuel.
Anyway, from what I have gathered is that the long term fuel trim parameter on any ECU is not precisely 0% and should be within range of -10% to 10% under normal running conditions. This is value formulated from the short term fuel trim which is dictated by the signal read from the primary oxygen sensor.
The prefl ep3's long term fuel trim value always resets to 0% for time the engine is started. This value is too ideal to be realistic and hence I'm curious to understand why this is the case. On my fl ep3 however, which has a different immobilizer system retains a value between -6% to -5.5% each time I start the engine. Based on this the prefl ep3 complied by the workshop which IMG (who did the aftermarket immobiliser) does not seems to persistently store the long term fuel trim value which my facelift ep3 does. Both use OEM ECU but compliance were done at different workshops.
Now the interesting observation and comparison from rear exhaust tip of both ep3s is that the prefl appears to be relatively darker with carbon soot than my fl ep3. This seems consistent with the fact the my fl ep3 is running relative leaner than the prefl ep3 based on long term fuel trim. Hence, I have a concern that the immobilizer always resetting the ecu (due to power cut off) and resulting the prefl ep3 running slightly richer than it needs to.
Anyway, just food for thought that got me curious.
Should be glad that not many others have a GENUINE mugen wing lol. :p
